HINGE LOCK.

Application filed May 26,

T all whom it may concern: Be it known, that I, LUDWIG Scorn, a citizenof the Republic of Switzerland, residing at Edgewater, county of Bergen,and State of New Jersey, have invented certain new and usefulImprovements in Hinge Locks, of which the following is a speolhcation.

This invention relates to nnprovements 1n hinge locks, particularlylocks for the hinges of step v ladders, when these ladders are to beused as straight wall ladders with their uprights locked in alignment.

Another object of the invention is the pro- I vision of a hinge lock forthe locking of sliding doors or hinged doors for preventing the entranceof burglars, etc., who may be successful in opening the customary doorlocks.

These and other like objects, which will become more fully apparent asthe description progresses, are attained by the novel construction, andcombination of partshereinafter described, and shown in the accompanyingdrawings, forming a material part of this disclosure, and in which-Figure 1 -is a top plan view of a hinge lock constructed according tothe present invention, particularly adapted to lock the hingesconnecting the uprights of a step 13d. der.

Figure 2 is a side view thereof.

Figure 3 is a detail side elevation of the locking member of the lock.

Figure 4; is'a detail side elevation of the keeper member of the lock.

Figure 5 is a fragmentary top plan view of the locking member. s

Figure 6 is a top plan view of the keeper member of thelock.

Figure 7 is a top plan view of a modified form of hinge lock constructedaccordin to my invention and adapted forlocking s iding doors. I

Figure 8 is a top plan view of another modified form of my inventionadapted for use with the customary hinged doors.

Figure 9 is a sectional side elevation of the keeper member of the hingelock, Fig. 8.

Figure 10 is a view similar toFigure 9 of, the locking member, and

Figure 11 is a sectional side view of both members in engagement, thesection being taken along line 1111 of Figure 8.

To the upper edges of the uprights 10 and 11 of a step ladder or thelike are secured by means of the screws 12 or the like,

the foot plate 13 of the locking member, and the foot plate'l l of thekeeper member.

The plate 14 is provided with longitudinal slots 15 forallowing anadjustment of the plate 14' of the keeper member by acorrespondingadjustment of the screws 12 with respect to the upright 11for a purpose which will be hereafter more fully explained.

The uprights 10 and 11 of a step ladder are connected at their loweredges by the customary hinges'16, and the plate 13 of the locking memberis provided at its inner upper end with an upstanding lug 17pr0- jectingsomewhat over theouter upper end of the upright 10 to engage in' arecess 17 of the upright 11 and having a central bore for the receptionof the pintle 18 to the ends of which at both sides of the lug 17 theears 19 and 20 at one end of the locking element or 'hasp 21 aresecured. Said hasp 21, is provided near its other end with-alongitudinal slot for the passage of the car 22 on the plate 14"throughwhich in thelocked position of theparts the shackle of a padlock 23 maybe guided, as indicated in dotted lines in Figure 1.

The inner end of the plate 1 1 is provided with two hook shapedprojections 24' and 25,

adapted to be engaged, when the parts are in their engaged lockingposition by lugs 26 at the end of locking member or hasp 21 laterallydisposed to the ears 19 and 20.

It will be clear that in place of the padlock an ordinary plug may beused and passed through the ear 22 of the. keeper member above thelocking member when it has been passed through the slot of said memberin order to lock the uprights or bars 10 and 11 of a step ladder inalignment when the ladder is to be used as an ordinary straight wallladder.

In the modified form of hinge look illus trated in Figure 7, which ispreferably to be used for the locking of sliding doors, the base plate27 of the locking member 27 is attached to one part 28 of a sliding doorby means of screws 29 or the like, while the keeper member 30 haslongitudinal slots 31 and is attached to the other part 32 of a slidingdoor by means of the screws 33 allowing an adjustment of the keepermember with respect to the door part 32. c I

The lock'ng member 27' has earsor perforated lugs 34: at the side edgesof its inner end through which are passed pintles 35 around the innerends of which are guided the forked ends 36 of the locking member 27.

The keeper member 30 has at its inner end a hook 37 adapted to engagebetween the forked ends 36 of the locking member and with its front end,when the locking member is in the position illustrated in Figure '7, theinner end wall of the same between said ends 36. It will be clear thatthis engagement of the hook 37 will prevent an opening of the slidingdoors when the parts are in the position shown in Figure 7, while aturning of the locking member 27 upon its base plate 27 will disengageits end wall from said hook so that both parts of the sliding door arefree to be opened and closed.

In the modified form of invention illustrated in Figures 811 inclusive,a door 38 is fastened bymeans of the customary hinges 39 to the doorframe 40- in the well known manner.

To the door 38 the base plate 41 of the locking member 42 is attached bymeans of screws 43 or the like, and the inner end of the plate 41 hasupstanding lugs 44 perforated in their center for the reception of thepintles 45 around the inner ends of which are rotating the forked endsof the locking member 42 which are shaped into ears 46.

The keeper member comprises a base plate 47 adapted to be secured to thedoor jamb 48 by means of pins or screws 49. or the like engaginglongitudinal slots 50 of the plate 47 and allowing a sliding movement ofthe same relative to the door jamb. This member 47 has an upstanding ear51 intermediate it-s ends adapted to be passed through a longitudinalslot in the locking member 42 and to receive the shackle of a padlock 52as indicated in dotted lines in Figure 8. i

, The outer end of thezkeeper member 47 is adapted to engage within asocket 53 secured to the door jamb 48 by means of a screw 54.

A leaf spring 55 is inserted in the socket 53 in the manner showninFigure 8 so that the outer end of the keeper member 47 engages with thisspring during the sliding movement of the member 47 on'jamb 48 in whichit is held by the slot and pin connection 49, 50.

The inner end of the sliding keeper plate 47 has a hook 56 adapted toengage the inner end wall 57 of the locking member 42 when the same isswung around into its locking position in which it engages the up perface of the keeper member 47 as illustrated in Figure 11.v The end wall57 is formed with a groove in which the hook 56 engages.

While the lugs 44 project somewhat over the inner end of the member 41the hook projects over the inner end of member 47 and it will be clearthat in order to allow an opening of the door after the locking member42 has been swung around its pivots into the position, Figure 10, themember 47 with its hook must be somewhat withdrawn or moved backwardagainst the action of spring 55 in order to allow a proper disengagementof the parts and an opening of the door 38.

Having thus described my invention, what I claim as new and desire toprotect by a United States patent is:

1. A hinge lock of the character described comprising a slotted lockingmember, a base plate to one end of which said locking member ispivotally secured, and a keeper member, a means for normally pressingsaid keeper member into locking position, said keeper member adapted tobe secured to a door, an eye in said keeper member adapted to be passedthrough the slot in said looking member and to receive the shackle of apadlock when said members are in alignment for locking them in thisposition.

2. A hinge lock of the class described comprising a slotted lockingmember, a base plate to one end of which said locking member ispivotally secured, a keeper member, two hooks atthe inner upper end ofsaid keeper member adapted to engage shoulders of said locking memberwhen the parts are in their locking position, and an eye on said keepermember intermediate the ends thereof adapted to be passed through theslot in said locking member when both members are in alignment and toreceive the shackle ofa padlock for keeping the locking member inposition in. said keeper member.

3. A hinge look of the class described for doors comprising a slottedlocking member, a base plate for said locking member adapted to besecured to a door, a keeper member adapted to be slidably secured to thejamb of a door by a pin and slot connection, a socket on said jamb intowhich one end of said keeper member engages, a spring in said socketnormally pressing said keeper member into its locking position, a hookat the inner end of the keeper member adapted to engage a groove in theend wall of the locking member, and an eye on said keeper member adaptedto engage and pass through the slot in said locking member for thereception of a padlock shackle guided through said eye above the lockingmember, and means for rotatably securing said locking member to theinner end of its base.

In testimony whereof I have aflixed my
